Same here. Always thought that, in my short lifetime at least, the Lyman GPR is the "best" mass produced(seriously loads of em second only to TC Hawkens) Hawken-esque gun made. It has the lines, and it is robust as can be from all accounts. Being a pawn broker, I have had a 54 cap GPR in the vault for a customer for 1.5 years and he has been paying interest on it the whole time. I only loaned him $100 because in a pawn shop BP MLs don't bring money. But he could have bought a used or even new one on sale for what he has payed in interest on it. If things go south and he can't get it back for some reason, I will give one a shot. Haven't bought a cap gun in a very long time.Little real experience with them but I like the way they handle and they do look really good.
A patched round ball and 70 to 90 grains of 2f powder, you won't need to max out the load.
